Two Onset HOBO UA-002 Temperature and light data loggers were each attached to a 4”x8”x16” concrete block that were tethered together with a length (~50 ft) of line so that no surface floats were needed. The depth at the site was shallow enough (3’) to see blocks on a calm day.
Both temperature loggers successfully collected data from the time they were deployed, May 10, 2022 through October 21, 2022.
